Boy I sure hope it wasn't a 36" or a 32" scale, since I use those for my fan fret designs. Haven't had any issues at all with those scales yet. But actually bad layout anomalies become very obvious on a fan, not to mention playing-wise. That is one of the risks I suppose relying on somebody else's calculations, a chance I took too.

I hope it's not catastrophic to your build.
